Yuri da Silva Villas Boas
Software Developer
Yuri graduated with a bachelor's degree in applied mathematics, with an emphasis in finance, and a master's degree in computer science from the Brazilian Federal Universities of Rio de Janeiro and Santa Catarina. He has excellent work experience in the design and verification of protocols, cryptography, proficiency in C++, and a solid background in statistics, physics, and mathematics. Yuri has developed Formosa, a password format, and SRVB, a public-key cryptosystem.

Work Experience
Information Security Analyst
Onyxcorp
- Created a viability assessment and quantitative comparative discussion of the adamant-based messenger app.
- Suggested an original ceremony for second device synchronization and activation.
- Developed a lay person-accessible article on Kerckhoff's principle.
- Built significant improvements to the security and usability of password interfaces.
- Constructed a go-to schematic diagram to determine the primary or secondary authentication protocols to be chosen from.
- Authored an original knapsack-based public-key cryptosystem.
- Revised and corrected several corporate advertisements and articles.
- Evolved into the go-to person in the company for questions on information security.
Software Analyst
Brazil National Institute of Pure and Applied Mathematics
- Created documentation in Latex for software written in R by F. Macias and his adviser professor, Dr. Jorge P Zubelli.
- Helped research and provide analysis for a thesis on the topic of the Optimization of Strategies of Liquidation of Options Portfolios. The thesis subject can be viewed as considering different approaches for a specific optimal stop problem.
Programmer
Federal University of Rio de Janeiro
- Developed new classes for a C++ simulation API by DEM Solutions, used in the Laboratory of Mining Technology (LTM) of UFRJ. In the Laboratory, the API is used to simulate milling in an attempt to energetically optimize this process.(http://www.edemsimulation.com/).
Programmer
Federal University of Rio de Janeiro
- Helped to develop a piece of software in C++ for the Mathematics Institute. The goal was to calculate the tau function in order to investigate the integer tau conjecture, an important conjecture in the field of Complexity (See "Complexity and Real Computation" - Blum et al.). My program calculated the inverse image of the Tau Function through depth-first search. The entire project was overseen by professor Gregório M. Muñoz.
- Added functionality for parallelization with Open MPI (a distributed memory architecture for parallelization).
- Optimized performance by working with GMP (GNU Multiple Precision), a library for arbitrary precision to express large integers.
Programmer
Federal University of Santa Catarina
- Developed C++ software in the Organic Opto-electronics and Anisotropic Systems Laboratory. The software has two functionalities - to calculate Interface Width and Height-Height Correlation of surfaces. (References: Marta Elisa Rosso Dotto "Universality of Scale Laws on Chemically Attacked Surfaces http://unicamp.sibi.usp.br/handle/SBURI/42157).
- Delivered a functional piece of software to the lab used daily by the team. This accomplishment is further supported by the fact that I had no knowledge of programming when starting the project.
